Services offered: 


Pre-formulation screening study

At HTL Biosolutions, Inc., we offer services focused on pre-formulation screening studies inculding pH screening, buffer screening, excipient screening, surfactant screening and preservative screening studies.  Our company founder and scientists have extensive experiences in designing appropriate screening studies to save you time and effort.  Novel combinations of appropriate screening studies shall also add useful data for potential patent applications.


Protein formulation optimization

At HTL Biosolutions, Inc., we offer technical services to optimize formulation parameters such as pH, salt concentration, stabilizer concentration, surfactant concentration etc.  The optimization of formulation parameters is essential to establish manufacturing specification parameters.  


Device compatibility study

At HTL Biosolutions, Inc., we offer customized services related to product-device compatibility study such as pre-filled syringe, auto-injector and syringe pump studies.  Protein therapeutics are normally susceptible to surface denaturation, and there are in-depth regulatory requirements on stability studies covering protein-device (primary container) compatibility.   We offer services focused on protein stability design and analysis, in combination with delivery devices.
